An incumbent senator who votes to confirm Judge Brett Kavanaugh to the U.S. Supreme Court is likely to gain Republican and independent voters in November but lose Democrat support.

A new Rasmussen Reports national telephone and online survey finds that 39% of all Likely U.S. Voters are more likely to vote for a U.S. senator in their state who votes to confirm Kavanaugh. Slightly fewer voters (34%) are less likely to vote for that senator. Just 20% say a confirmation vote for Kavanaugh would have no impact on their voting decision in November.

The survey of 1,000 Likely Voters was conducted on September 9 -10, 2018 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC. See methodology.
